My new war driving rig looks very similar, this week I’ve got my first Raspberry Pi (Model B) and put it together with two Alfa Wifi adapters, a Garmin GPS18x USB, USB hub and Newtrent IMP120D powerpack into a household box that fits into a small backpack.

The first results looks promising but not spectacular in comparison with my Android Phone (about 100% gain in found networks.)

I've ordered parts for a similar rig, with a Raspberry Pi (Model B), one Alfa AWUS036H Wifi adapter w 9dBi antenna, a BU-353 GPS, a Newtrent IMP120D powerpack and a couple of class 10 SD cards. My Pi won't come until Friday, so I'm stuck staring at the parts until it comes.

In the meantime, I've been running with two Android phones simultaneously. I've found that running two phones picks up about an extra of 10% to 20% more APs than running with just one phone. It also is (obviously) redundant, so when one device craps out (or runs out of batteries or has problems) the other device is there and running. This is working well, and I'm currently in #2 spot for most APs found this month - although some of this can be blamed on my wife being out of town and being located in Southern California with a lot of density around me - at best, I can hit about 1K APs an hour.

thwiggle - by 100% gain in comparison to Android, do you mean that you're seeing double the APs?

Also, what is the blue-ish Alfa Wifi "N" adapter you're running, and what are the advantages to running it?

thwiggle - I'd like to hear more details about how you've configured your Raspberry Pi - especially if you're running Kali Linux and what you did to configure it.

Bigstape answered some of your questions already, i'm still finetuning and testing the box but did see once about double the AP's (100% gain), on another trip I found 50% more networks compared to my Android phone.

If you have some exprerience with Linux it would not be that hard to configure the Raspberry Pi, just unzip the NOOBS package on your SD card, and install Raspbian (recommended). I've no experience with Kali Linux. The Alfa Wifi adapters were supported out-of-the box under Raspbian, just use apt-get to install some additional GPS packages etc...

Kismet compiled without any problems, I just put kismet-server in my /etc/rc.local startup script.

I'm not getting as good performance as I'd hoped out of my Pi: my Android phones running find more APs (due to scanning at 50ms, I think) - although my Pi finds ones further (due to a better antenna, I think).

Does anybody know ways to improve the performance of Kismet on a Pi? (I'm new to Kismet.) When modifying kismet.conf and increasing the channel hopping speed ('channelvelocity') from 3 to 5, my Kismet UI almost completely freezes up - I haven't run any tests with this yet, though.

RasPi with a GPS Addon board (source: http://ava.upuaut.net/store/index.php?r ... duct_id=95) to make a really simple, compact kit. I have since replaced the GPS antenna with one that has a MUCH shorter piece of coax, so I'm not having to deal with a huge bundle of cable.

Unit is, of course, powered from any standard USB charger, but IMPORTANT to note that the charger needs to provide greater than 1 ampere of current at 5VDC. Some chargers are limited to less than 1 amp, and those will cause problems.
